You’ve probably heard about beer made from leftover bread, but how about beer made from rain water? Rainbeer makes beer from collected rainwater throughout the Netherlands.
Amsterdam-based startup Rainbeer works with local brewers throughout the Netherlands who collect rainwater from the brewery’s rooftops and turn it into beer.
Rainwater is collected from the rooftops which passes through a filter. The rainwater is completely purified by a micro filter, an activated carbon filter, a membrane filter and a UV filter . With this purified rainwater, the brewer brews fresh rain beer.
According to Rainbeer, rainwater is ideal for making beer since it is softer than tap water and contains fewer minerals. Some connoisseurs claim the softness also ensures that the bitterness of the beer comes into its own.
Rainbeer started life in response to the Netherlands’ heavy rainfalls, which are directly linked to climate change. Rainbeer co-founder Joris Hoebe saw rain’s potential as a raw material for beer brewing.
Rainbeer says: “Due to climate change it rains more and more often and there are also longer periods of drought. That is why we need to be more aware of our (rain) water.
“At the moment we see rainwater as waste, in the built environment we transport it as quickly as possible to the sewer or outside the city. This must be done differently if we want to create a climate-adaptive city. Collect the rainwater and turn it into something! Beer for example.
“Rain is a local raw material. The rain in Amsterdam is different from rain in Nijmegen.The city of Amsterdam is different from Nijmegen. With this local beer we want to start the conversation around the climate and rainwater use.”
Rainbeer currently sells six different rain beers from five different brewers throughout the Netherlands.
